In case of TDS deduction and Payment Y does not the TIN/NSDL Website provide FREE SOFTWARE?

If our Society is liable to deduct TDS from the Contractor:-
01. Does the TIN/NSDL provide the Free Software for this? Why the hell are we supposed to spend on the Software from authorised Software Providers like Tally or Sensys Technologies,etc.?
02. For the purpose of liability what is the Limit and is it dependent on the actual Payments made in a Financial Year or the Total Contract Value?

Kindly note that the limit of 1,00,000 is applicable w.e.f 1.6.16, prioir to that it was 75,000
Therefore if in the month of April or May, the limit of 75,000 was exceeded then there was TDS liability.
